Abstract: A method of manufacturing a sterile stack of peelable lenses includes coating a first lens (or stack of lenses) with a first adhesive coating, heating the first adhesive coating to initiate curing, exposing the first adhesive coating to ultraviolet light to continue curing, laminating a second lens (or stack of lenses) onto a surface of the first adhesive coating to produce a stack of lenses, coating the second lens with a second adhesive coating, heating the second adhesive coating to initiate curing, exposing the second adhesive coating to ultraviolet light to continue curing, laminating a third lens (or stack of lenses) onto a surface of the second adhesive coating to add the third lens to the stack of lenses, and exposing the stack of lenses to an electron beam to continue curing of the first and second adhesive coatings.

Abstract: Manufacturing a pre-molded stack of one or more lenses to be installable on a curved substrate such as a vehicle windshield includes placing a moldable stack of one or more lenses and adhesive layer(s) on a mold, applying heat and pressure to the moldable stack to produce a pre-molded stack of one or more lenses from the moldable stack, and removing the pre-molded stack from the mold. The pre-molded stack may have a compound curvature, which may match a curvature of the curved substrate. The mold may be formed using three-dimensional shape data derived from the curved substrate, such as by optically scanning the curved substrate.

Abstract: A process for preparing a composite of two or more continuous phases, one which is tantalum carbide or a mixture of tantalum carbide and carbon which comprises(1) impregnating a preform of graphite or a similar material in the form of a porous block or woven fiber form with a reactive carbon source such as petroleum pitch, a coal tar pitch, a thermal setting resin, or a sugar;(2) pyrolyzing the reactive carbon source to form carbon;(3) impregnating the preform with either Ta(OCH.sub.3).sub.5 or Ta(OCH.sub.2 CH.sub.3).sub.5 under anhydrous conditions;(4) hydrating the Ta(OCH.sub.3).sub.5 or Ta(OCH.sub.2 CH.sub.3).sub.5 to precipitate Ta.sub.2 O.sub.5 throughout the preform; and(5) heating the preform at a temperature of 1400.degree. C. or more until the Ta.sub.2 O.sub.5 has reacted with the carbon to form tantalum carbide.

Abstract: The method of coating ceramic whiskers selected from the group consisting SiC, graphite, boron carbide and alumina with magnesium by sublimation and finally by magnesium oxide (MgO) after oxidation comprising(a) heating powdered Mg and SiC.sub.w mixture in an oxygen free atmosphere to a temperature of 400.degree. C. to 550.degree. C.(b) igniting the mixture in air in the presence of O.sub.2 (which may incidently cause the mixture to attain a temperature more than 1800.degree. C.) that the desired end results in a coating of MgO on the whisker or particle surfaces, to obtain novel coated whiskers varying in length from 10-100 microns.
